Which of these variables is the largest component of the GDP? If people decide to spend less on any additional income they receive, how does that impact the multiplier?
GDP components are consumption (C), Investment (I), government expenditures (G) and net export (Xn). All of them are important but the degree of importance depending on the economy. Certain economies rely more on C, while some others are relying more on I, some on G and some on Xn.
